IEEE 1474
CBTC Performance and Functional Requirements
IEEE 1474 is a functional safety or safety-assurance reference for Rail & Transit. It defines the expectations teams use to turn hazards into requirements, evidence, reviews, and release decisions.
Use it when customers, regulators, assessors, or internal safety governance need a defensible standard-specific argument. The exact scope depends on the product, market, safety functions, and lifecycle phase.
CSA helps interpret the standard, assess gaps, prepare certification evidence, train teams, and staff experienced safety engineers or assessors.
